It should certainly be enough

The CPU cooler Dark Rock Pro 4 is sufficient for TDP 250 W. As the Intel i5-14600K CPU only burns TDP 125 - 181 W, this cooler is more than sufficient.

I don't know . I mounted this heatsink for an older processor with a view to mounting it for Generation 14.

Of course! More than enough.

Should be enough. Runs here on Ryzen 7800X3D mostly under 65° when gaming.
